Wycombe will be without midfielder Lewis Montrose when Hereford come to Adams Park on Boxing Day.
Montrose was scheduled to return from suspension against the Bulls but will instead sit out a one-match ban after last weekend's trip to Southend fell foul of the freezing weather.
However, the Chairboys are very confident that Sunday's fixture will take place which will allow Gary Waddock's side to continue their decent form.
Dagenham & Redbridge midfielder Stuart Lewis extended his loan deal this week and he will now be with the club until the end of January.
Defender Leon Johnson could make his 100th appearance for the Chairboys and striker Jon-Paul Pittman continues his recovery from a ruptured knee tendon which is expected to keep him out until the new year.
Josh Parker (foot) remains the only other long-term injury concern and the midfielder will not feature for at least six weeks.
Hereford are again without Sam Gwynne.
Gwynne was due to miss last weekend`s postponed fixture against Macclesfield having picked up a hamstring injury and has failed to shake it off in time for the clash at Adams Park.
Fellow defender Ryan Green also misses out as he serves the final game of his three-match suspension, with Ryan Valentine and Dan Connor (both hip) long-term absentees.
Manager Jamie Pitman, last Thursday confirmed in the role until the end of the season, has no other concerns as his squad prepare to travel to Buckinghamshire, with Wanderers confident the encounter will get the go-ahead thanks in large to their undersoil heating.
